Description

Technical Field

[0001] The utility model relates to the technical field of culture bottles, in particular to a dense connective tissue culture bottle. Background Art

[0002] Dense connective tissue is primarily composed of cells and a large amount of intercellular matrix, which is primarily composed of matrix, filamentous fibers, and continuously circulating tissue fluid. In biomedical research, scientists use culture flasks to culture cells or tissue fragments isolated from dense connective tissue. In vitro culture allows for a deeper understanding of the structure and function of dense connective tissue.

[0003] The utility model patent with authorization announcement number CN202021341204.9 discloses a new type of tissue culture bottle, which includes a base, a bottle body and a top cover, the top of the base is connected to the top cover through the bottle body, a first annular groove is provided around the top of the base and around the bottom of the top cover, the top and bottom of the bottle body are fixed with a first annular protrusion, a through hole is passed through the middle of the top of the top cover, a second annular groove is provided in the middle of the top of the base, a culture tank is provided on the top of the second annular groove, a second annular protrusion is fixed around the bottom of the culture tank, a rotating disk is connected to the middle of the bottom of the culture tank through a connecting shaft, a water filter screen is installed in the middle of the interior of the culture tank, the top of the water filter screen is filled with culture soil, pull ropes are fixed on both sides of the top of the water filter screen, an annular cone plate is fixed around the top of the water filter screen, and guide rollers are installed on both sides of the top of the culture tank. When the user needs to observe the conditions inside the culture bottle in all directions, the user can slowly rotate the rotating disk to rotate the connecting shaft, and then drive the culture tank to slide and rotate in the second annular groove through the second annular protrusion, thereby changing the orientation of the culture tank in the culture bottle, making the observation process more convenient and labor-saving, and avoiding the situation where observation is inconvenient during use of the culture bottle.

[0004] Although the new tissue culture flask has the advantage of convenient observation, the device still has the following problems in actual use: the culture flask is not equipped with a light-shielding structure, and when dense connective tissue and other substances are cultured under light, light of different wavelengths will affect the microorganisms or other biological factors in the culture environment, thereby indirectly affecting the growth and improvement of dense connective tissue. Light of specific wavelengths may also directly act on the photosensitive receptors on the dense connective tissue cells, thereby easily affecting the culture results. In view of this, we propose a dense connective tissue culture flask. Utility Model Content

[0005] The present invention aims to at least partially address one of the technical problems in the related art. To this end, one object of the present invention is to provide a dense connective tissue culture bottle that, by enclosing a light shield around the exterior of the bottle, prevents direct light exposure from affecting the culture of dense connective tissue within the bottle, thereby ensuring optimal culture results for the dense connective tissue.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] This embodiment provides a technical solution:

[0029] See also Figure 1-Figure 4As shown, a dense connective tissue culture bottle includes a base 1, a light shielding assembly 2 is fixed on the top of the base 1, and the light shielding assembly 2 includes an accordion-shaped and retractable light shield 20 fixed to the top of the base 1, a connecting ring 21 is fixed on the top of the light shield 20, and two slots 210 are formed on the top of the connecting ring 21, and a sliding cavity 212 is formed on one side wall of the slot 210, and a spring 22 is installed at the end of the sliding cavity 212. A slider 23 is also slidably installed in the sliding cavity 212, and the end of the spring 22 is pressed against the slider 23. The slider 23 A plug 25 is fixed at the end of the base 1; a detachable bottle body 3 is also installed at the top center of the base 1. The bottle body 3 is transparent and is installed in the openings of the light shield 20 and the connecting ring 21. A light shielding plate 31 is fixed on the top of the bottle body 3. The top of the connecting ring 21 is pressed against the light shielding plate 31. Two plug blocks 32 that are plugged into the slots 210 are fixed at the bottom of the light shielding plate 31. A socket 320 is provided on one side wall of the plug block 32, and the plug 25 is plugged into the socket 320; a bottle mouth 33 is installed at the top center of the light shielding plate 31.

[0030] In this embodiment, a sealing cap 34 is threadedly connected to the bottle mouth 33, and a plurality of anti-slip grooves are provided on the outer wall of the sealing cap 34. The threaded connection facilitates the assembly and disassembly of the sealing cap 34, and the plurality of anti-slip grooves enhance the convenience of use and effectively prevent the hand from slipping when rotating the sealing cap 34.

[0031] In this embodiment, the bottle body 3 and light shield 31 are integrally molded, and both are made of polystyrene. This integrated design improves the stability and reliability of the connection between the bottle body 3 and light shield 31. The choice of polystyrene, due to its excellent light transmittance, corrosion resistance, insulation, and processability, makes the bottle body 3 and light shield 31 both lightweight and durable.

[0032] In this embodiment, a threaded post 30 is coaxially and tightly bonded to the bottom of the bottle body 3, a threaded groove 10 is formed on the top of the base 1, and the threaded post 30 is threadedly connected to the threaded groove 10. This design facilitates installation and disassembly while ensuring a stable and sealed connection.

[0033] In this embodiment, the outer wall of the connecting ring 21 is provided with two centrally symmetrical strip grooves 211. A lever 24 is slidably mounted within the strip grooves 211. The distal end of the lever 24 is fixedly connected to the slider 23. By moving the lever 24, the position of the slider 23 can be easily adjusted, thereby facilitating the assembly and disassembly of the connecting ring 21, thereby achieving flexible adjustment of the position of the light shield 20.

[0034] In this embodiment, the light shield 20 is tightly bonded to the connecting ring 21. Both are made of rubber. Rubber has excellent elasticity and sealing properties, effectively blocking light while also providing a certain cushioning effect, protecting the cultured cells from external impact. The tightly bonded top further enhances the stability and sealing of the entire culture device.

[0035] In this embodiment, the cross-section of the base 1 is trapezoidal, and the base 1 is tightly bonded to the light shield 20. The trapezoidal design increases the contact area between the base 1 and the placement surface, improves the overall stability, and prevents tipping due to accidental touch during operation.

[0036] It should be added that the surface of the light shielding plate 31 in this embodiment is coated with black light-shielding pigment. This design helps the light shielding plate 31 to have a light-shielding effect, which is conducive to cultivating dense connective tissue in the bottle body 3.

[0037] During specific use, the user first pulls the connecting ring 21 upwards, and the connecting ring 21 drives the light shield 20 to move upward, and the light shield 20 is stretched at the same time. Then the user pushes the lever 24 to one side, and the lever 24 drives the slider 23 to slide along the sliding cavity 212, and the spring 22 is compressed. At this time, the slider 23 drives the plug 25 to retract into the sliding cavity 212. When the plug 32 is inserted into the slot 210, the user releases the lever 24. Under the elastic action of the spring 22, the slider 23 drives the plug 25 to be inserted into the socket 320, and the connecting ring 21 is fixed to the light shield 31. At this time, the light shield 20 covers the outside of the bottle body 3 and blocks light from entering the bottle body 3.
